WRENCH. I

To allwhbm it may concern: 8 I Be it known that I, JOHN W. KLINE, a citizen of the United States, residing at White Haven, in the county of Luzerne and State of Pennsylvania, have invented a new and useful'Wrench, 'of which the following is a specification,

This invention relates to a wrench of that known as monkey wrenches, in which a straight stem or stock is provided with a fixed jaw and a movable jaw slidable on said stem to adjust the wrench for grasping articles of various sizes.

The object of this invention is to provide combination a Wrench having jaws for turning articles of olygonal section such as bolts and nuts, an separate jaws 'for'rotating those that have a circular section, pipes androd's, for instance, the movable jaws in bothcases'formed on or attached to a unita y'fr'ameg, 1 7

Another object of the invention is to provide a simple and quickly acting mechanism for disconnecting the unitary movable jaws from the'shan'k so that they can slide freely thereon to any position desired,- then applied to the article' to be turned, roughly ad usted and locked in place and finally set b the usual worm or screw common to wrencli es of this class. r l f -With these and'other' objects in view, the inventionconsists of the novel construction,

arrangement of parts .hereinafter described and definitely claimed.

In the accompanying drawings :Figure 1 is an elevation of the improved wrench. Fig. 2 is a similar view partly in section. Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.

Similar numerals of reference indicate the same parts on all the figures.

of mesal provided on one side with a series of teeth near one end, to which end a head 3 is attached or formed integrally therewith. The head 3 preferably extends laterally beyond the stock on opposite sides thereof as ipldicated by 4 and 5. The under face 6 of t e the stock 1, said extension forming the fixed jaw of the wrench for operating on polygonal articles. The opposite extension or jaw 5 is concaved on its under side and i'ovi ded with teeth 7 which bite on and he (1 cylindrical articles to be rotated. I

The unitarvmovable jaw frame8 1S -adapt' Specification. of Letters Patent. Application filed April'25. 1907. Serial no; 370.244.

the extension 16 of extension 4 is fiat and perpendicular .to'

jaw frame 8 to ti t worm 9 from the teeth 2. The aw frame can 11!) ed to slide freely on the shank 1, but may be locked thereto in such manner that it can only move by rotating the screw or worm 9 which engages the teeth 2 on one side of the stock. Onthe movable jaw frame 8 under the fixed jaw 4 is a jaw 10 having a flat face 11 adapted to cooperate with the face 601 the fixed jaw. A jaw 12 having a convex face in opposition to the concave face of the fixed jaw 5 is pivoted to the jaw frame 8 opposite the jaw 10, and has teeth 13 similar to the teeth 7.. I

The jaw frame 8 is cut away at 14 below the pivoted jaw to permit it for one purpose 7 0 to swing and disengage the worm 9 from the teeth 2. Below the jaw 10 the jaw frame 8 is cut away which is seated the worm 9 pivoted on the smooth upper end of a the notch. A companion extension 17 projects from the movable jaw frame-8 on the opposite side of the shank 1 and is made hol low with an inclined outer I mission of the bolt or wedge 18 which also has a side of the same inclination as said outer wall and when in place is in contact with it. The lower part of the wedge or bolt 18 is curved outwardly to form an operating 85' end or hook 19 for sliding it, and on its inner side or' side next the of metal 20 preferably steel, extending above the wed e or bolt, to which is, attached at its end a b ock 21 short distance. Fastened to the outer side of the block 21 is a fiat spring 22 its up erpart parallel to the strip 20 for a short istance, and is then bent into an offset 23 just above the extension 17, to form a stop. Con- 95 tinuing downwardly from the offset 23 but at an angle, the spring lies in a slot 24 on the outer lnclined face of the extension 17, and finally terminates with a sh ht inwardly curved end 25 above the hook sh When is is desired to move the jaw frameS, a finger of the hand isplaced below the curved end 25, and the spring 22 lifted until the offset 23 is'drawn over the upper edge of the extension 17,-as indicated I Fig. 2. The bolt or wedge 18 is then drawn downwardly, carrying the spring 22 withit, and the latter bein to one side',;freeing the now be moved freely u and downthe stock at w1l1,"and so soon as t e desired position has Patented Y to form a rectangular notch in,

In testimon that I claim the foregoing as my own, I ave hereto aflixed my s1gna ture in the presence of two witnesses.
